How Are Foam Screening Splines Manufactured?

September 15, 2022

Foam screening splines are used to create a seal between the screen and the frame of a window or door. They are made of foam and fit into a groove in the frame. Screening splines come in different sizes to fit different-sized screens. There are several methods of manufacturing foam screening splines, each with its own advantages and disadvantages. In this article, we will take a look at how these splines are manufactured.


How Are Foam Screening Splines Manufactured?

The extrusion process is the most common method of manufacturing screening splines. In this process, molten polyethylene is forced through a die that has the desired cross-sectional shape of the spline. As the substance cools, it solidifies and takes on the shape of the die. This method can produce very consistent results and is relatively quick and easy.
Once the foam screening splines have cooled and solidified, they can then be cut to length as needed. They can also be cut into different shapes if desired. For example, some companies will cut them into circles so that they can be used as doughnut-shaped gaskets. Other companies will cut them into long strips so that they can be used as seals for doors or windows.
How polyethylene foam is used for manufacturing screening splines:
Polyethylene foam is a type of plastic that is often used for packaging and insulation purposes. It is also frequently used in the manufacturing of screening splines. Screening splines are thin strips of plastic or metal that are used to secure screens in door and window frames. They are typically made from polyethylene foam because it is easy to work with and is relatively inexpensive.
Even the installation of screening splines is easy. Once you remove the old screening spline, you can install a new one by following these steps. First, apply the adhesive backing to the spline. Next, press the spline into place and hold for a few seconds until it is secure. Finally, trim off any excess with a utility knife or razor blade. You can rely on Alcot Plastic Ltd. if you are looking for a dependable manufacturer of foam screening splines.
